Abstract
Foundations of structures like earth retaining structures, abutments, waterfront structures, machines, oil/gas platforms in offshore areas, etc. are subjected to eccentric and/or inclined loading. The contact pressure below the foundation does not remain uniform due to eccentric load as the foundation tilts. Response of a rectangular foundation on the surface of the ground modeled as non-linear Winkler model is evaluated for its dependence on eccentricity of load, subgrade properties, etc. The ultimate bearing capacity of eccentrically loaded foundation is not only a function of width of the footing and eccentricity of load but also depends on the compressibility of the foundation soil. The ultimate load ratio of eccentrically loaded foundation with respect to concentrically loaded foundation is estimated based on both Meyerhof’s method and the proposed approach. The predicted values of ultimate load ratio compare well with the measured ones.
